X2Y Fil t e r & De c o u p l i n g
ca pa c i t o r s
X2Y® filter capacitors employ a unique, patented low inductance design featuring two balanced
capacitors that are immune to temperature, voltage and aging performance differences.
These components offer superior decoupling and EMI filtering performance, virtually eliminate
parasitics, and can replace multiple capacitors and inductors saving board space and reducing
assembly costs.
Ad v A n tA g e s
